Examples of org.apache.muse.core.routing.ResourceRouter

org.apache.muse.core.routing.ResourceRouter
ResourceRouter is the gateway to the generic resource layer that sits on top of the isolation layer. It is generic because it has no platform-specific dependencies - it uses raw SOAP and WS-Addressing data to match requests with the resources being targeted by the client. The isolation layer simply extracts this data in the platform-specific way and then delegates control to the ResourceRouter, which further delegates to an individual {@linkplain org.apache.muse.core.Resource Resource object}. There should only be one ResourceRouter per application. @author Dan Jemiolo (danj)
